Handover Control is one of the essential means to guarantee the continuity of mobile services to a user traveling in a cellular infrastructure, without interruption. In previous work we illustrated that using the current 3GPP specified handover control algorithm to provide continuity of MBMS (Multimedia Broadcast Multicast Service) services to a user crossing cell boundaries results either in capacity or QoS inefficiencies and proposed a new MEHO (Mobile Evaluated Handover) based MBMS handover control algorithm that compensated for them. This algorithm, although effective in terms of capacity and QoS, has some limitations concerning the way certain parameters vital for the efficient MBMS handover execution are estimated. In this paper, using a different approach (Network Evaluated Handover (NEHO)), we enhance previous work and propose a different method, that eliminates all of its predecessor's deficiencies while achieving the same capacity and QoS efficiencies. © 2008 IEEE.
